Methane is a potent greenhouse gas and as an air pollutant it contributes to tropospheric ozone formation, which is detrimental to health. About 60% of total global methane emissions stems from anthropogenic emissions, and about 40% from natural sources. In 2022, Europe contributed to 5.2% of...

Air pollution, especially ground-level ozone, poses severe threats to human health and ecosystems. Accurate forecasting of ozone concentrations is essential for reducing its adverse effects. This study aims to use the functional time series approach to model ozone concentrations, a method less...

Catalytic ozonation is an effective technology widely used in advanced treatment to remove refractory organics from wastewater. Meanwhile, it is also a highly energy-consuming technology, usually accounting for 30%~40% of the total electricity consumption of a wastewater treatment plant (WWTP)....

This study successfully developed a nanocomposite catalyst (Co2SnO4@rGO) at optimal composite ratio of 2:1 between Co2SnO4 and GO for effectively activation of peroxymonosulfate (PMS) to degrade cefalexin (CFX) from aqueous solution by hybrid ozonation system (O3/Co2SnO4@rGO/PMS). The CFX...

This paper revisits one of the rare success stories in global environmental cooperation: the Montreal Protocol and the phase-out of ozone-depleting substances. I show that the protocol increased science and innovation on alternatives to ozone-depleting substances, and argue that agreements can...

The Coordinated Activities on the Safety of Products (CASP) projects enable all the market surveillance authorities (MSAs) from European Union (EU) / European Economic Area (EEA) countries to jointly ensure that unsafe products are swiftly removed from the Single Market. This activity focused on...

In light of the low public awareness of ozone pollution and the potential health threats posed by long-term ozone exposure, this study estimates the causal effect of long-term ozone exposure on respiratory mortality. By employing an instrumental variable based on the long-distance transmission...

Lactose in cheese whey wastewater (CWW) makes it difficult to degrade under normal conditions. The effect of ultra-sonication (US), ozonation and enzymatic hydrolysis on increasing the bioavailability of organic matter in CWW and biogas production were evaluated. The pre-treatment conditions...

Ground-level ozone is a continuing problem worldwide, but research on the influences of ozone pollution on labour productivity in developing countries is insufficient. We investigate the effect of ozone pollution on outdoor worker productivity in the service sector using a unique panel dataset...

China has exerted great efforts in the past decades to fight against particulate matters and has achieved initial results, but ozone pollution has increased significantly. Using a unique diagnostic data of a peninsula city in China, this study evaluates the health effect of ozone pollution on...

Catalytic ozonation was adopted for treating the brine derived from a two-stage reverse osmosis (RO) treatment in bio-treated coking wastewater reclamation. The preparation parameters of Mn/γ-Al 2 O 3 and Mn-Ce/γ-Al 2 O 3 catalysts were optimized. The effects of operating conditions on the...

Ozonation of wastewater can reduce the release of organic micropollutants, but may result in the formation of undesirable by-products, such as bromate from bromide. Bromide is one of the most abundant ions in seawater, the primary precursor of bromate during ozonation, and the end product in...

2020 presented the ideal conditions for studying the air quality response to several emission reductions due to the Covid-19 lockdowns. Several studies found that the tropospheric ozone increased its concentrations in many countries even in lockdown conditions, but its reasons are not entirely...

Black-odor water not only completely loses the function, but also seriously affects the environment landscape and human health. Aiming at the problems of high cost and low activity of catalysts for black-odor waters treatment by catalytic ozonation technology, this paper fabricated a stable...

Microplastics detected in potable water sources and tap water have led to concerns about the efficacy of current drinking water treatment processes to remove these contaminants. It is hypothesized that drinking water resources contain nanoplastics (NPs), but the detection of NPs is challenging....

The inactivation of antibiotic resistant bacteria (ARB) and genes (ARGs) in an advanced plant combining ozonation and granular activated carbon (GAC) filtration applied for effluent after conventional activated sludge treatment at a full-scale urban wastewater treatment plant was investigated...

Continuous measurements of ozone (O3) and nitrogen oxides (NOx=NO+NO2) were conducted from 2007 to 2019 in Hong Kong in order to evaluate the effectiveness of control strategies for NOx emission from diesel commercial vehicles (DCV). DCV control programs were periodically applied in three phases...

Working fluid preparation using treated drilling wastewater is of great potential for drilling wastewater reuse, especially in water-deficient and ecologically fragile areas, which require low levels of organic matter and suspended solids. This study established the dissolved ozone flotation...

Non-methane hydrocarbons (NMHCs) are a group of low molecular weight compounds containing only hydrogen and carbon atoms in the C 2 -C 12 range, not only acts as a major precursor for the formation of O 3 through oxidation, but also cause several health problems. Cooking oil fume (COF) is one of...

Satellite data reveal that China has significantly increased its vegetation cover since 2000, and vegetation will maintain the increasing trend in the foreseeable future for becoming carbon neutral. However, limited work has examined the environmental impacts of vegetation greening because...

Previous studies on ozone pollution primarily focus on the characterization of ozone on a large regional scale, yet much less attention has been paid towards the contrast between urban and surrounding suburban-rural areas. As anthropogenic emissions are projected to decrease in the coming...

Much of human exposure to ozone takes place indoors. However, few studies have focused on the impact of design variables on residential building envelopes’ capacity to prevent outdoor ozone from penetrating through the envelope into interior spaces. To investigate the potential for outdoor...

We present a proof-of-concept analysis of the measurement of the health damage of ozone (O3) produced from nitrogen oxides (NOx = NO NO2) emitted by individual large point sources in the eastern United States. We use a regional atmospheric model of the eastern United States, the Comprehensive...

In the absence of first-best climate policy, we demonstrate that existing government institutions and policy established for reasons unrelated to climate change may induce climate adaptation. We examine the impact of temperature on ambient ozone concentration in the United States from 1980-2013,...
